## Ejemplo
|
|
|
|
```go
|
|
db, err := PostgresOpen("localhost", 5432, "user", "secret", "mydb", "disable")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer DBClose(db)
|
|
|
|
rows, err := DBQuery(db, "SELECT id, name FROM users WHERE active = $1", true)
|
|
```
|
|
|
|
## Notas
|
|
|
|
Usa el driver `github.com/jackc/pgx/v5/stdlib` registrado como "pgx". Construye DSN con los parametros separados para mayor legibilidad. Para produccion usar `sslmode=require` o `sslmode=verify-full`. Hace ping al abrir para verificar conectividad.
